In vitro propagation method was developed for obtaining large number of plantlets of Valeriana wallichii DC. (Valerianaceae), an indigenous high value medicinal and aromatic plant species of Indian Himalayan region, using nodes of in vitro grown seedlings. High frequency shoot proliferation was induced in explants cultured on Murashige and Skoog (MS) medium supplemented with different concentra...

The aim of the present study was to evaluate the central effects of the phytotherapeutic product-CPV (dry extract of Crataegus oxyacantha, Passiflora incarnata and Valeriana officinalis) in animals models. In order to investigate the psychopharmacological profile of CPV extract, an evaluation toward anxiolytic effect of this extract on the elevated plus-maze (EPM) was carried out. Other effects...

Three new germacrane-type sesquiterpenoids, heishuixiecaoline A-C (compounds 1-3), were isolated along with ten known compounds 4-13 from fraction of Valeriana amurensis roots and rhizomes effective against Alzheimer's disease (AD). The structures of 1-3 were elucidated on the basis of their spectroscopic data. We also investigated the protective effect of compounds 1-13 on the neurotoxicity of...

In Germany since 1980, more than 300 clinical studies have been carried out with standardized phytopharmaceuticals, including Crataegus, Silybum, Ginkgo, Hypericum, Sabal, Urtica, Kava-Kava, Allium sativum, Valeriana, Aesculus, Echinacea, and Viscum drugs. These studies assessed the efficacy of phytopharmaceuticals for the treatment of moderate or moderately severe diseases and prevention. Seve...

The pharmacological effects on the central nervous system (CNS) of a range of available flavonoid glycosides were explored and compared to those of the glycosides 2S-hesperidin and linarin, recently isolated from valeriana. The glycosides 2S-neohesperidin, 2S-naringin, diosmin, gossipyn and rutin exerted a depressant action on the CNS of mice following i.p. injection, similar to that found with...

In some medicinal plants a specific plant-fungus association, known as arbuscular mycorrhizal (AM) symbiosis, increases the levels of secondary plant metabolites and/or plant growth. In this study, the effects of three different AM treatments on biomass and sesquiterpenic acid concentrations in two IN VITRO propagated genotypes of valerian ( VALERIANA OFFICINALIS L., Valerianaceae) were investi...
